    NEW YORK (AP) — In the opening moments of the documentary “Gleason,” the celebrated New Orleans Saints safety Steve Gleason talks to the camera with a not-yet-occupied crib behind him. He has just learned that he has ALS. Soon the symptoms will take over. Preparing for what’s coming, Gleason tells his unborn son that he wants to give him “as much of myself as I possibly can while I still can.”

    New technique opens window into how brain cells communicate

    WASHINGTON (AP) — The brain’s nerve cells communicate by firing messages to each other through junctions called synapses, and problems with those connections are linked to disorders like Alzheimer’s and epilepsy. Now Yale University researchers have developed a way to picture synapses in living brains.
